1. 使用镜像
1.1 在Docker Hub上查找镜像
我们查找一下之前博客里面，推送到Docker Hub里面的bage88/docker-demo，能看到有2个仓库，第一个就是我们上次上传的镜像。点击“Details”进入到详细页面。
1.2 拉取镜像到本地机器
在我们本地虚拟机上执行如下命令，获取该镜像：
docker pull bage88/docker-demo
1.3 了解我们获取的镜像
下载完成之后，通过docker images查看当前机器上已经有的镜像列表。
通过docker inspect IMAGE_ID或者docker inspect IMAGE_NAME查看镜像详细信息。

2. 使用容器
2.1 以bash shell方式运行容器
# -i ：打开并保持容器的标准输入
# -t ：分配pseudo-TTY终端并绑定到容器的标准输入上
docker run -t -i bage88/docker-demo /bin/bash
进入容器中，我们可以查看到我们之前复制文件到镜像里面的内容。执行命令
root@ubuntu-512mb-sfo2-01-gfw:~# docker run -t -i bage88/docker-demo /bin/bash
root@94a1f3581ebb:/# cd /usr/share/nginx/html
root@94a1f3581ebb:/usr/share/nginx/html# ls -l
total 12
-rw-r--r-- 1 root root 537 Oct 11 2016 50x.html
drwxr-xr-x 2 root root 4096 Apr 19 01:10 images
-rw-r--r-- 1 root root 669 Apr 19 01:10 index.html
root@94a1f3581ebb:/usr/share/nginx/html#
2.2 以daemon进程方式运行容器
我们常见的Web应用，应该是让容器一直运行，所以需要创建以daemon方式运行容器。
# -d ：daemon方式运行容器，退出终端，程序还在运行
# -p ：允许指定Host主机一个端口和容器内部一个端口进行隐射。
docker run -d -p 8010:80 bage88/docker-demo
在浏览器访问Host主机的IP+端口，结果如图所示：
2.3 查看容器
查看当前运行的所有容器docker ps -a
2.4 删除容器
删除容器的命令：
docker rm CONTAINER_ID
